Iran victory within Obama's reach

US President Barack Obama has won the backing of a fresh clutch of senators for his Iran deal, raising the prospect he could yet dodge a humiliating legislative rebuke. For months, Republicans and rebellious Democrats have looked on course to pass a resolution against the nuclear deal, a stinging rejection of a central Obama foreign policy goal. A ‘no’ vote next month would not be enough to scupper the whole nuclear agreement — thanks to Obama’s veto power — but it could foreshadow trouble ahead.
